I have a question about hairpin NAT. When doing hairpin between two interfaces of FGT, do I have to create/use public VIP for the source and destination? I found out it works without NAT as well. What type of specific case do I have to use NAT? Thank you.
The hairpin VIP is desirable when a laptop/mobile user wants to use the same public IP (NAT outside IP) even when moved into the office and connected internally as well as accessing it from the internet.

For internal IPs, if you're a hacker, there are many ways to figure out what they're like by scanning the ports. The problem is the hacker got inside. But yes, you can block direct access if you want for security reasons.
